Overview
Each October, the American Branch presents International Law Weekend (ILW) in New York City. This two-and-a-half-day conference features over 30 panels, and many of the world’s leading international lawyers and diplomats participate. In recent years, keynote luncheon speakers have included the president of the American Society of International Law and the Legal Adviser to the U.S. Department of State. Gala receptions have been hosted by the Finnish, Belgian, British, and Singapore missions to the United Nations.
Recent ILWs have attracted an audience of over 1,200 practitioners, academics, U.N. diplomats, business leaders, federal and state government officials, NGO leaders, journalists, students, and interested citizens. Registration for ILW is very reasonably priced as a service to our members. It is free for students. Sponsorship by law firms, universities, and interested practitioners is welcomed and recognized.

International Law Weekend 2025:
Crisis as Catalyst in International Law
ILW 2025 will place on October 23-25, 2025 in New York City.
The unifying theme for ILW 2025 is Crisis as Catalyst in International Law, as follows:
ILW 2025 will explore how crises can serve as transformative moments that challenge and reshape the framework of international law. Whether political, environmental, economic, or humanitarian, crises compel local, regional, and global actors to confront the limitations of extant legal systems. By serving as catalysts for innovation, crises also provide opportunities to reevaluate and reconstruct international legal norms. This process highlights the dynamic nature of international law, which must balance its foundational principles with the need for flexibility in response to unprecedented events. ILW 2025 encourages participants to reimagine international law.
ILW 2025 will explore these issues through a diverse set of engaging and provocative panels, plenary sessions, and keynote addresses. The program will include a broad array of both public international law and private international law topics. The conference will also include networking opportunities, social events, and award ceremonies.

International Law Weekend 2024:
Powerless law or law for the powerless?
ILW 2024 took place October 24-26, 2024 in New York City.
The unifying theme for ILW 2024 was Powerless law or law for the powerless?, as follows:
International law faces an existential threat as history unfolds at unprecedented speed worldwide. Indeed, international law and international institutions at times appear incapable of protecting vulnerable persons against war, disease, hunger, exploitation, climate change, and other human and natural catastrophes. Some people–both individually and collectively–are openly eschewing legal values and frameworks in order to pursue results through other means, including dangerous and destabilizing ones. Is international law, in fact, powerless or does it remain a source of power that vulnerable persons can utilize to protect and advance their rights and interests? This year’s ILW is focused on engaged, interactive, and inclusive discussions about how international law can transcend perceptions and misperceptions of its powerlessness and fulfill its aspirations of balancing power through principles of justice, equality, and dignity.
Dedication: In honor of the 100th anniversary of the 1924 Geneva Declaration of the Rights of the Child, ILW 2024 was dedicated to the promise of the Declaration’s preamble recognizing that humanity owes to children the best that we have to give.
